All information on this page is courtesy SPUI. This page is an attempt to catalog different sources of Bergen County's route numbering. Presumably, the SLD (first column) numbers are the most accurate for the present-day route numbers, though SLD errors do often exist, and the "official" Bergen numbers are closer to what you'll find in the field. "Bergen map" refers to the official Bergen County map, or at least the one they present to those who request one, though the latest editions do not have route numbers.
